We might not know the sex or name of the Duke and Duchess of Cambridge's baby, but it was announced yesterday, we do know that due to a change in rules regarding the title of the child, they will titled 'Princess' or 'Prince' if it is a boy.
Previously, if a girl was born to the royal couple, she would have been known as 'Lady' and not 'Her Royal Highness'. A boy would automatically be a 'Prince' but only the eldest son. But now the Queen has taken steps to ensure that all Kate and William's children will be 'Prince' and 'Princess' by issuing a new Letters Patent.
A notice in the London Gazette made the announcement: "The Queen has been pleased by Letters Patent under the Great Seal of the Realm dated 31 December 2012 to declare that all the children of the eldest son of the Prince of Wales should have and enjoy the style, title and attribute of royal highness with the titular dignity of Prince or Princess prefixed to their Christian names or with such other titles of honour."
The news was revealed on Kate Middleton's 31st Birthday. The Duchess marked the occasion “privately” according to Clarence House and is rumoured to have spent it in North Wales where she lives with Prince William.

The change in title is the latest move by the Queen to modernise royal practice. It comes as plans continue to revise succession laws that would make he royal couple's child monarch regardless of sex.
